STEAM-G EN ERATOR OR WATER-H ETER.

SPECIFICATION forming part of Letters Patent No. I709,006, dated September 16, 1902. Application filed April 7, 1902. Serial No. 101,734. (No model T0 all whom t may concern.-

Be it known that I, BERNARD A. GEUEINK, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ollio, have invented certain new and useful Improvements in Steam-Generators or Water-Heaters; and I hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in steam-generators or water-heaters, and more especially to the construction and relative arrangement ot the sections comprising the water-circulating and flue-forming portion of the heater.

The object of Athis invention is to construct the water-circulating portion of the heater of interchangeable and corresponding sections arranged compactly at different elevations, respectively, and having the passageways formed therein sloping upwardly toward their discharging ends and arranged and connected to form a continuous passage-way from the inlet of the lowermost section to the outlet of the uppermost section.

Anotherobject is to so relatively arrange` the iuid conducting passage ways of each water-circulating section and to so place each section relative to the adjacent section or sections that products of combustion employed in heating the said sections shall not only be most economically'utilized to the best advantage, but that the water fed to the said sections is quickly heated and most advantageously circulated.

Another object of my invention is to render the construction simple and durable and convenient in the assemblage of the parts and for making repairs.

With these objects in view my invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a side elevation, partly in section, of the water-circulating and fine-forming portion of a steam-generator or water-heater embodying my invention. Fig. II is a top plan of the same. Fig. III is a side elevation in central Vertical section. Figs. IV and Vare central vertical sections taken at right angles to each other of a water-circulating section of the heater.

The water-circulating portion of a steamgenerator or water-heater embodying my inven tion is composed of several cast-metal sections ct, compactly arranged, respectively, in a horizontal plane at different elevations, re-

spectively, and in line vertically, and the heater illustrated in the abovementioned drawings has four of the said sections a, which are circular in plan, correspond in construction,and are interchangeable. Each section ct is provided at the bottom and centrally with an internally-scrow-threaded vertical induction-port or water-inlet a', which depends below the remainder of the said section. Each section a is provided at the top and centrally with an upwardly-discharging eduction-port or water-outlet d5, which is arranged in line vertically with the inductionport or water-inlet ct of the said section, which port or outlet aff extends above the remainder of the said section, and the surrounding wall of the said port or valve a5 has external screw-threads corresponding with the internal threads of the aforesaid port or inlet a', so that each section a can be screwed at its water-inlet a' onto the section a next below at the water-outlet a5 of the last-mentioned section. Each section a is provided with two fine-forming apertures or openings b and b, which extend vertically through the said section at opposite sides, respectively, andexternally of the ports of and a5 of the said section. Each section a is provided interiorly with four passage-ways a2, a3, a3, and a4, :which slope, respectively, upwardly toward their discharging end. Thepassageways as and d3 are formed at the outer side of the dierent flue-forming openings b, respectively, of the said section a, and the passage-ways a2 and d4 are formed between the said openings b at opposite sides, respectively, of the ports a and of the said secl tion. The passage-way a2 communicates at its lower and inner end with the inductionport a of the said section d and discharges at its upper and outer end into the lower ends of the passage-Ways a3, which communicate at their upper and discharging ends with the lower end oi' the passage-way a4, which IOC) communicates at its upper and discharging end with the eduction-port a5 of the said section. Each section is provided between its passage-ways co2 and c5 with an impert'orate partition c, which prevents direct communication between the said passage-ways and causes all of the water or iiuid conducted to the said section at its induction-port ct to pass, first, upwardly through the aforesaid passage-way c2 between the two tine-forming openings h of the said section, thence upwardly through the passage-ways a3 around the outer sides of the said openings I), and thence upwardly through the aforesaid passage-way co5 between the said openings Z) to the eduction port c5 of the said section. Each section a has such arrangement relative to the adjacent section or sections a that the flue-forming apertures or openings b of each section ce are out of line with the {ine-forming openings l) of the adjacent section or sections a, so that the path of the products of combustion employed in heating the said sections and passing upwardly through the openings Z9 of the lowerm ost section a is circuitous, and the said products of combustion during their upward passage from the openings b of the said lowermost section are distributed and circulate around all portions of the sections a, and the said upward passage of the products of combustion is retarded or rendered sufficiently slow to utilize them most economically and to the best advantage. It will be observed also that the construction of the sections a is simple and durable, that packing of joints in the assemblage ofthe sectionsctisdispensed with, and that the said sections ct are readily assembled and as quickly and conveniently separated for repairs, renewal, and cleaning.

In Figs. l and IIl a water-supply pipe te is shown connected with the induction-port at' of the lowermost section a, and in the same figures and in Fig. Il is shown a pipe y for conducting steam or hot water from the eduction-port a5 of the uppermost section a.

l would here remark that my improved heater comprises several sections arranged at different elevations, respectively, and each section of the heater essentially has the following: an induction-port or Huid-inlet arranged at the bottom and centrally ofthe section, an upwardly-discharging eduction-port or fluid-outlet arranged at the top and centrally of the section a suitable distance above the induction-port, a lower sloping passageway ct', an upper sloping passage-way 61,4,and two intermediate sloping passage-ways (t3 and a3, with the lower passage-way Ct/ and the upperpassage-way Mai-ranged at opposite sides, respectively, of the aforesaid ports, with the lower passage-way ct/ extending laterally outwardly and upwardly from the inductionport, with the upper passage-way a4 arranged a suitable distance above the upper end of the lower passage-way d and extending laterally outwardly and downwardly from the education-port, and with the two intermediate passage-ways a3 and a3 arranged at opposite sides, respectively, of the lower and upper passage-ways d' and 0,4 and connecting the upper end of the lower passage-way a with the lower end of the upper passage-Way a4 and gradually sloping upwardly from the lower passage-way c', so that fluid passing upwardly from the said lower passage-way c' is divided at the upper end of the said passage-way between the intermediate passageways a3 and a3 and passes continuously upwardly in its passage upwardly through the heater.

What l claim is- 1. A heater of the character indicated, comprising several sections arranged at different elevations respectively, and each section provided with an ind uction-port or fluid-inlet arranged at the bottom and centrally of the section and anupwardly-discharging eductionport or fluid-outlet arranged at the top and centrally of the section, and each section, except the lowermost section, communicating, at its induction-port, with the Yeduction-port of the section next below, and each section also having the following: a lower sloping passage-way, an upper sloping passage-way and two intermediate sloping passage-ways, with the lower passage-way and the upper passage-way arranged at opposite sides, respectively of the ports of the said section, with the lower passage-way extending laterally outwardly and upwardly from the induction port, with the upper passage-way arranged a suitable distance above the upper end of the lower passage-way and extending laterally outwardly and downwardly from the ed notion-port, and with the two intermediate passage-ways arranged at opposite sides respectively of the lower and upper passageways and connecting the upper end of the lower passage-way with the lower end of the upper passage-way and gradually sloping upwardly from the lower passage-way.

2. A heater of the character indicated, Comprising several sections arranged at different elevations respectively, and each section provided with an eduction-port and an induction-port arranged at the top and bottom respectively and centrally of the section, and each section, except the lowermost section, communicating, at its induction-port, with the eduction-port of the section next below, and adjacent sections having mutually-engaging threads at their communicating ports, and each section also having the following: a lower sloping passage-way, an upper sloping passage-way and two intermediate sloping passage-ways, with the lower passageway and the upper passage-way arranged at opposite sides respectively ofthe ports ot the said section, with the lower passage-way extending laterally outwardly and upwardly from the induction-port, with the upper pas- IOO IOS
